What is PHP?

PHP (Hypertext Preprocessor) is a popular open-source scripting language for web development. It works behind the scenes on the web server to create dynamic and interactive websites. PHP allows websites to process user input, interact with databases, and display personalised information.

PHP is a long-standing programming language renowned for its free use and high compatibility with major operating systems. It offers many tools that simplify coding. Its cross-platform nature also makes collaboration easier among web developers. Additionally, PHP’s high performance helps websites load faster, making it a strong choice for web development.

To make it easy to understand:

Imagine visiting an online store and adding an item to your cart. Instead of forgetting what you chose when you move to another page, PHP works in the background to save your selection. When you check out, PHP retrieves the stored information, calculates the total, and processes your order. This makes websites more interactive and functional rather than just displaying static content.
